No A, no B – 沒 méi A 沒 méi B

Grammar Point:
沒 méi A 沒 méi B, literally “no A, no B,” is used to emphasize a complete lack of certain things—usually two related nouns or qualities—and is often spoken in a casual, emotional, or disapproving tone.

It’s important to note that this structure isn’t something you can just use with any words — it’s usually limited to a few set phrases and works more like a fixed expression.
